Robert Zemeckis directed the project for Paramount Pictures.

The movie will see Pitt and Cotillard as assassins who fall in love during a mission in Casablanca to kill a German ambassador. A future together, however, is thrown into tumult when twisty secrets from their pasts cast doubts on their love for each other.

Steven Knight (The Hundred Foot Journey) penned the script.

Graham King will produce the film under his GK Films production banner. Knight will serve as executive producer, alongside Jack Rapke, Patrick McCormick and Denis O’Sullivan.

Zemeckis recently released the biographical drama The Walk, starring Joseph Gordon-Levitt, which has earned an underwhelming $38 million at the worldwide box office to date.
